Grinning of the pile loops, d of obviated by tyin the ile" his- Although a plain weave is formed by employing one set of weft-threads a, and two warp-threads to the face of the fabric and firmly held in position over the weft-threads -a, in each set of the weave throughout the sheds of the fabric, as is the case in the roduction of the fabric of Fig. 1. Aside om being of less stiffness as to the body thereof, the woven pile tuft fabric-of Fig. 2 does not differ from the fabric illustrated in Fi 1.

In order to place the pile tufts or threads d, directly over the weft-threads a, in each shed throu bout the fabric, the binder warpthread'c, and stuffer warp-thread b, are depressed as shown in Fig. 1, and the pile tufts or threaded, are first conducted around the warp-threads c and moved forwards to the place of weaving by mechanism to be hereinafter more fully described. After the pile tufts or threads dhave been shifted to their proper position, the weft-threads a are shot into the shed so formed directly beneath the loop at, of the pile tufts or threads (1, as-indicated in dotted lines in Fig. 1, after which the stuffenwarp-thread b,is raised and the second weft-thread a, and pile tufts orthreads (1, are now beaten up by the lay e, in the usual well known manner and brought into alinement with each other. For the formation of the 'succeeding shed, both'the binder warp-threads c and the stuffer Warpthreadb, are lowered, while at the same time,

' the binder warp-thread c, is raised into the pile tu position occupied by the thread a, in Fig. 1, and so on in regular sequence throughout in the fabrication of the woven pile fabric. By the beatin up of the weft and pile tufts or threads, the pile tufts or threads (1, are brought very close together, and rest side by side ormi thereby in the fabric produced by the we t-th'reads a and a, and warpthreads 1;, c and c, apile tuft surface of reat density and in which each of the ile tu ts or threads d is bound on the face of t e fabric by the binder warp-threads c and c and each held above a weft-thread a. The pile tufts or threads d, thus securely held between the warp-threads and weft-threadwillbe locked against removal or pulling-out. The thread employed for forming the pile or tufts of the fabric may consist either of a seriesof single threads or tufts, as shown in Figs. 1 and 2, or

may betformed of a series of thin fluffy.

threads ad libitum, bound or tied by the warp-threads in separate sheds throughout, as hereinbefore described.

The preferred mechanism for inserting the ts or threads (2, around the binder warp-threads occu ying the raised position, is as follows :As s iown in Fig. 1, each of the pile tufts or threads (1, is conducted through a feeding finger f, consisting of a fiat metal tube j, which is curved upwardly as at f and is bent sidewise at the free end thereof, as at f The feeding fingers f, are supported by a bar h, which is raised and lowered and partially turned in a vertical plane and is shifted forwards in a raised position, in a horizontal plane, by any suitable mechanism, not shown. Each of the fingers is provided at its curved portion f wit a knifelike projection f which, when the fingers are depressed,aid in the proper insertion of the feeding fingers f, between the warp-threads. The pile tufts or threads d, which are supplied to each of the feeding fingers f, by a spool or other means of su port, not shown, project a certain distance om the free ends f and are conducted around a warp-thread in the following manner: When the fingers f, are lowered by the bar h, the same will pass between the warp-threads, in the present instance, the warpthreads 0 during which downward movement the free ends f thereof, owing to their location sidewise of the shanks f of the fingers f, will move the warpthreads sidewise. As soon as. the fingers f, are brought with their free endsf, below the warp-threads c, the same released from the pressure exerted thereon by these ends will return to their normal straight position and the projecting ends (1", of the pile tufts or threads (1, which were first conveyeddownward at one side of the warp-threads 0 will be moved over the same, and upwards on the other side of the warp-threads, as shown in' turning of the feeding fingers from straight to obli ue positions and the movement of the warp-t eads by a specially arranged comb to conduct pile threads around the warpthreads, as is the case in the U. S. Patent No. 723,342, dated March 24th, 1903, is effectuallyovercome. The ends (i of the pile tufts or threads (1, projecting from the fingers f, above the warp-threads c, are now engaged by clamping bars '11 and i supported and actuated by means, not shown, and are held'in position by the same. The fingers f, by means of the bar h, are now brought out of engagement with the warp-threads by a combined turning and u ward movement in' the same plane, in which the fingers de scended, by which movements the free ends f, of the fingers f, are moved from one side of the warp-threads to the other side thereof,

and by being brought into the first osition shown by dotted lines in Fig. 1, con uct the pile tufts or threads (1, which are held at by dotted lines in Fig. 1, and by this movement the pile tufts or threadsd, are brought to the point for weaving the fabric. After t i pile tufts or threads have thus been properly placed on the warp-threads c knives k is now introduced into the shed directly be low the pile loop d, as shown by the dotted lines in Fig. 1, and after closing the shed and beating up the pile tufts or threads (1, and

weft-threads, the pile tufts .or threadsinserted in a manner such as hereinbefore described, will be securely held and bound by the Warp-threads. By such arrangement each finger f, is adapted to introduce pile threads differing in color from adjoining pile threads and hence the number of colors that may be employed to produce apattern ordesign in a Woven pile fabric, is. unlimited.

Moreover, by the particular outline and shape of the feedingfingers f, theremaybe used as many fingers as there are-warpthreads,-andhence the pile'tufts or threads will not only rest side by side in a longitudi- Anal plane in the fabric, but also in a plane transyersely thereto.

Having thus described the nature and ob.-

jects of my invention, what I- claim as new.

and desireto secure-by Letters Patent is 1. In awoven pile fabric, two binder Warp-threads, weft-threads, and interwovensepa ately cut pile tuits or threads bound bythe Warp-threads occupyinga raised p0s1.-
